Neurons have three crucial parts: the soma, the dendrites and the axon. The soma is where the nucleus and the cell proper of the neuron is. The dendrites recieve information from other neurons and transmit it to the soma. The axon is the "talker" sending information from the soma of the neuron to other neurons. The axon is long and thin, makes up most of the neurons length and depending what type of neuron the cell is, the axon could be encased in a "protective layer of fat called the Myelin Sheath". In contrast, dendrites are numerous, fat and bushy.
